项目描述

Xvid (formerly XviD) is an open source MPEG-4 video codec, implementing MPEG-4 Simple Profile, Advanced Simple Profile, and Advanced Video Coding standards. It is written in C with assembler optimizations for quality and speed (including MMX, SSE, and 3Dnow! code for i386 and AltiVec for PowerPC), and is especially optimized towards offline, multi-pass compression for storage and archival purposes.

1.1.0-beta1

此试用版的发行，只有几处改动的API，这是非常接近1.0.x分支。该库仍然可以使用基于与客户端应用程序1.0.x.
标签: Development, Major feature enhancements
This beta release has an API that is very close to the 1.0.x branch, with only few changes. The library can still be used with client applications based on 1.0.x.

1.0.3

固定非常小错误，这是解放和源代码和二进制与以前的版本兼容。网格优化溢出的定量小于或等于2是固定的，流过短不再阅读，防止无用的垃圾流阅读，和64位，由于发生事故处理假设32位整数是固定的。两个钻石搜索错误是固定的，其中之一是造成错误的方向搜索，另一导致出局。
标签: Minor bugfixes
This release fixed very minor bugs and is source and binary compatible with the previous version. Trellis optimization overflows for quant smaller than or equal to 2 were fixed, streams that are too short are no longer read, preventing the reading of useless stream garbage, and 64-bit crashes that occurred due to addressing assuming 32-bit integers were fixed. Two diamond search bugs were fixed, one of which was causing searches in wrong directions, the other causing an early exit.

1.0.1

直流misprediction的缺失值裁剪造成的错误所引发的1fps的解码器，在网格错误这是造成后期块跳绳，和我的错误，可能导致结果不理想的bframes序列已得到修复。在比特率的计算错误时，由于比特率和尺寸（2.4％）已得到修复。 ICM的兼容性已经增加了对办公套件（OpenOffice.org，MS办公室等）。更多已知的音频文件类型已被添加。
标签: Major bugfixes
DC misprediction caused by missing value clipping, bugs triggered by 1fps sequences in the decoder, a bug in trellis that was causing block skipping in later stages, and an ME bug that could cause suboptimal results for bframes have been fixed. An error in bit rate calculation when given the bit rate and size (2.4%) has been fixed. ICM compatibility has been added for office suites (OpenOffice.org, MS Office, etc.). More known audio file types have been added.
